将 UITapGestureRecognizer 添加到 UIWebView-移动开发问题

Add a UITapGestureRecognizer to a UIWebView(将 UITapGestureRecognizer 添加到 UIWebView)

本文介绍了将 UITapGestureRecognizer 添加到 UIWebView的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在 iOS 中，是否可以在 UIWebView 上放置一个点击识别器，以便当有人单击 Web 视图时执行一个操作?

In iOS, is it possible to put a tap recognizer on a UIWebView, so that when someone single-taps the web view, an action gets performed?

当我点击我的 webView 时，下面的代码似乎不会触发 handleTap.

Code below doesn't seem fire handleTap when I tap my webView.

谢谢.

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self 
                                                                      action:@selector(handleTap)];
tap.numberOfTapsRequired = 1;

[webView addGestureRecognizer:tap];
[tap release]; 


-(void) handleTap {
    NSLog(@"tap");
}

推荐答案

我发现我必须实现这个方法才能让它工作:

I found that I had to implement this method to get it to work:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}
